Looking for some replacement rings for my TS1 200 , so 66mm, should i stick to Wiseco brand or will Wosner or genuine Yamaha rings be ok.

If the same thickness, shoud be ok, but check the ring ends, some cover the pegs, some curve round them

thanks for that, as i would be buying online ive no way of checking the ends.
I cant find any Wiseco in uk stock,all suppliers seem to be over the pond

If I could find the online catalogue to show you the variations of ring that Wiseco manufacture, I would do so.

In other words, there are several types of profile in addition to the material to suit the variations in bore material.

Assuming the piston is an original Asso then AF might have some?

No, it`s a wiseco IT175 piston, i use a RD400 rod, 115mm.
Wiseco part no. 2598CD, plenty on google but all in USA.

cant you go to a local trails iron /crosser shop with the piston to see if they can help you out bud?
I'm sure I've got the ref no on a box with a new piston & ring packet, that I'm using on a project

I have various NOS Wiseco pistons & rings but I'd need to check against the ring part number you require to see if I have a match.

I also have a complete IT175 piston that did about 50 miles in a TS cylinder before the owner commissioned a complete rebuild comprising a 70 mm top end. I have not looked @ it since removal to see what manufacture it is or suss out the grade, though I suppose I could get it measured

Eastwoods have supplied me with various Wiseco pistons in the past and will do replacement rings...

thanks for that info, but will they fit Wiseco piston?

soz bud they're for a Yam IT175 piston

I'll have a look in my Sudco catalog and give them a ring to see if they've got any. And, they don't. They are available direct from Wiseco https://powersports.wiseco.com/wiseco-p ... -81-2598cd

They are also available on Amazon.com. https://www.amazon.com/Wiseco-374M06600 ... 900&sr=8-1

I'm pretty sure Amazon will ship international.

thanks FnF

Are CD rings fine to run in Nikasil bores (Alloy steel, ferrox coated, chrome faced, internally notched)

I thought the best choice would be the otherwise identical CDM (Nodular iron, phosphate coated, internally notched for use in • Chrome Bores)

No idea, but been running them for at least 5 years.
Haven't even stripped the engine down yet, just thought i`d look for rings now rather than later.
Got some on Amazon for £35.00
thanks to all for imput

Thankfully..... we dont have chrome bore cylinders, (which would have to be used with cast rings if we did.)
Nikasil is compatible with virtually any type of piston ring makeup. Cast rings would just wear out quicker than anything else.
